Navy Blue Fondant???

Can anyone give me some help on making navy blue fondant for a baseball cap? Should I just purchase navy food coloring? I've read a lot on here that dark deep colors are hard to achieve. Never tried a dark color like this and am not sure. Thanks

I use the Americolor "Navy Blue". It will achieve a nice dark Navy for you without having to add any other colors. I have cakes in my photos with Navy Blue buttercream and fondant roses, etc.....All were colored with the above.

Rather than putzing around with paste colors I buy pre-colored satin ice and use those color to custom blend what I need. It makes life SO much easier (and less messy lol). Satin ice also has a mixing chart available for some basic colors (but you can use other charts available online for more blending options). Just another option!
